I don't mean to consider which languages are the best for writing poetry in, since you would need to be equally familiar with all languages.  But which ones have, so far, yielded the best poetry?  Poetry is important in cultural identity and in expressing the beauty of language, philosophy, emotion.

Persian, Latin, Italian, Classical Greek, English, Japanese, Arabic, Chinese, and Hebrew come to mind.

"Por isso tomo ópio, é um remédio. Sou um convalescente do momento, moro no rés-do-chão do pensamento e ver passar a vida faz-me tédio." - Fernando Pessoa.

Portuguese rules!

I don't see how you can leave out French, German, Spanish and Russian.

Since that rounds out all the languages I've ever studied, I think I conclude that great poetry can be written in any language whatsoever.

I read (past) english, french, italian and spanish poetry

For "light" and beauty love poetry, french sound very good, then, italian.

I like english, but always sound cold.

For a more deep poetry, spanish is very good, french and italian sound trifling.

"Caminante, son tus huellas
el camino, y nada más;
caminante, no hay camino,
se hace camino al andar,

Al andar se hace el camino,
y al volver la vista atrás
se ve la senda que nunca
se ha de volver a pisar.

Caminante, no hay camino,
sino estelas en la mar. "

Antonio Machado (1875-1939)

Old Norse, of course! How could you forget... Got a thick book crammed with this stuff at my shelf. Really a shame i can't really read it, but at least they say it's very sophisticated 

ARABIC is Poetry

that was for whom can read Arabic

Norman influence gave many nouns, like pork, beef, dame.  But the majority of words created in the last 600 yrs are from graeco-latin origin.  Modern English has hundreds of thousands of words, whereas English during the Norman times was far more limited.  Along with this most suffixes/prefixes are latin/greek.  Shakespeare alone invented scores of words and essentially all of them were from classic origin, or derived from it.

Azimuth, Does the second distich say that the taste of death for a worthless thing is the same as for an important thing?

yes

Poems of Khayyam are wonderful, in the last robai, there are five Tobe with five different meanings.

konam shab tobe = to repent tonight
labaa'lab tobe = lips on your lips
tobe kojast = where are you?
ze tobe Yaarab tobe! = between you and the God, you are better!

When you say Rumi do you mean Mevlana Celaleddin Rumi or some other Rumi?

in my opinion, chinese poetry is really amazing. it's attached to emotion, feeling, and lots of deep meaning in few words with rythm. however, when it's translated into other languages, it loses some most important characters.

if u dun read/ understand classical chinese, you will never be able to feel that emotion.

You are right about his life, but in fact, he was Turkish. Mevlana Celaleddin Rumi was a Turkish poet who used mostly Persian language...
